HOMEWOOD, Alabama -- Hundreds of Homewood students jumped at a chance to establish a Guinness world record today.

More than 1,000 at the city's high school and nearly 800 at the middle school performed jumping jacks for one minute at their respective school campuses.

The event is apart of first lady Michelle Obama's "Let's Move in School" campaign to to combat childhood obesity. The first lady asked schools and communities to participate in the jumping jack event to help set a world record, said Nivada Spurlock, Homewood schools wellness coordinator.

To set the record, 20,000 people had to do jumping jacks for one minute within a 24-hour period, starting 3 p.m. Tuesday, Spurlock said.

Homewood school officials won't know whether they've set the record until all of the sites participating in the event have been accounted for, which could take a few weeks, Spurlock added.
